What is CP23 primarily focused on?

CP23, or Conservation Practice 23, is primarily focused on the establishment of buffers for the restoration of wetlands. These buffers are critical as they help to filter pollutants, reduce erosion, and improve water quality by providing a transition zone between the wetland and adjacent land uses. The practice emphasizes the importance of maintaining healthy wetland ecosystems which offer numerous benefits, including habitat for wildlife and support for biodiversity.

In the context of the other options, while marginal pastureland wildlife habitat, bottomland timber establishment, and pollinator habitat are each important conservation practices, they do not specifically align with the intended focus of CP23. Each of these other practices may serve valuable environmental functions, but they address different dimensions of conservation compared to the targeted restoration and protection work emphasized in CP23 related to wetlands and their buffers. Therefore, the primary focus remains squarely on wetland restoration buffers, which are crucial for managing and enhancing wetland functions.
